Storm water drains and sewer drains are two completely different drainage systems. To avoid cross contamination of the water in your home the pipes must be installed correctly and should not join together.
Stormwater is water that comes from your roof, your subsurface drains or your stormwater pits, and runs through the storm water pipes and out to the stormwater drain at your kerbside or down the back of your property into a council stormwater drain.
Stormwater is considered clean water and ends up going out to sea, therefore it can’t be contaminated with sewage from your sewer drains.
The most common issues with stormwater drains are:
- Stormwater runoff
- Blocked stormwater pipes or drains
- Damaged stormwater pipes
- Incorrectly installed stormwater pipes
This occurs when rain falls and water lays around instead of soaking into the ground or draining away to a stormwater drain. This usually occurs on concreted or paved areas where natural drainage isn’t possible.
Blocked stormwater pipes or drain
This occurs when stormwater cannot drain away, due to a blockage in the pipe work. This can be caused from leaves or debris building up in your guttering, which could get flushed through with heavy rain causing a blockage in pipes. Tree roots can cause blockages in pipes, which can rapidly grow and cause a blockage.
Damaged storm water pipes
If your storm water pipes are damaged, you could get a backup of water as it can not drain away properly due to damaged or collapsed pipes.
Incorrectly installed storm water pipes
Tree roots can enter pipes through poorly installed joins of piping or misaligned pipes. This is usually due to unprofessional installation where short cuts have been made.
